  lavfi/opencl : Avoid deprecation warnings when built with post-1.2 headers
  The intended target is OpenCL 1.2, so disable warnings for APIs deprecated
  
  after that.  This primarily applies to clCreateCommandQueue(), we can't use
  
  the replacement clCreateCommandQueueWithProperties() because it was
  
  introduced in OpenCL 2.0.
  Also remove some unnecessary includes from overlay and program filters so
  
  that the define is available at the right moment.

  i am submiting this form

   <form style="margin:0px;display:none;" action="videoupload.php" method="post">
  
              <input type="file" style="display:none;" />
  
              </form>

  to the page above
  when ever i submit the form i get the error no file added like as if the post variable is not getting there on the page and when i remove the validation

    if(!isset($_POST['profileimage99']) || $_FILES["profileimage99"]["size"] ==''){
  
  echo 'No file added';die;
  
   }

  i can upload some files usually less then 2 mb file but for larger files i get undefined index error for profileimage99.

  i have increased the upload_max_size from php.ini file

  Please not that the form is submitted by ajax call
